SECTIONAL VENTILATING-CHIIVINEY.

SPECIFICATION forming part of Letters Patent No. 515,482, dated February 27, 1894.

Application led September 13,1893. Serial No. 485,387. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL H. RICHMOND, a citizen of the United States, residing at Norn walk, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sectional Ventilating-ChiInneys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

M y invention has for its object to provide an Inexpensive, durable and perfectly safe chimney or liuc for houses, and which shall furthermore be adapted to serve either as a heating or Ventilating line or for both purposes simultaneously.

With these ends in view I have devised the novel sectional Ventilating chimney which I will now describe referring by numbers and letters to the accompanying drawings forming part of this specification in which- Figure 1 is an elevation of my novel chimney set up, a roof and lioor being indicated In section; Fig. 2 a section on the line a: in Fig. l; Fig. 3 a horizontal section on an enlarged scale on the line yy in Fig. 4,'showiug each iiue made in two sections; Fig. 4 a vertical section the line being indicatedby z z in Fig. 3; Fig. 5 a plan view and Fig. 6 a section of an ordinary simple form of union for securing the outer half sectionsftogether; Fig. 7 a plan view and Fig. 8` a section of another form of union which is intended to carry a damper; Fig. 9 a section corresponding with Fig. 3 illustrating another way lof assemblingl the sections; Fig. l() a detail'end elevation illustrating a form in which the chimney is made square above the roof and also showing the roof plates; Fig. 1l a detail side elevation corresponding therewith; Fig. l2 a horizontal section on the line sein Fig. 1l looking down showing the inner iiue made in four sections and the sections assembled in still another way, and Fig. 13 is a detail sectional view on the line wwkin Fig. l2 the chimney being omitted but its relative position indicated by dotted lines. i

A denotes the inner flue and B the outer lines. Each of these iiue'sis made in sections denoted respectively by a and b and the sets of sections are connected by unions C. The sections and unions may be made of any suitable material. I preferably however make them of iron and cast the parts the exact shape required.

An important feature of my invention is that the parts are all interchangeable.

The sections of the inner flue comprise arc shaped portions 5 each section being provided on one side near its edge with outwardly eX- tending-lugs 6 and on the other side with an outwardly extending flange 7 which may, as in Figs. Band 5, have on its outer face a groove Sand is provided at its extreme end with an enlargement 9.

The sectionsof the inner fine are assembled as clearly shown in Figs. 3, 9 and l2, the edges of the arc shaped portions engaging the other sections, and lugs 6 lying in contact with flanges 7 to which they are secured by bolts 10.

The assembled inner iue is held central in and is securely fastened to the sections comprising the-Wall of the outer flue as shown either in Figs. 3, 9 or l2.

Inpthe form illustrated in Fig. 3 the sections ot the outer flue are provided at their ends with thickened portions ll which correspond with each other and in the meeting edges of which are formed recesses l2 which receive the enlargements 9.

. In the form illustrated in Fig. 9 ianges 7 are made relatively longer and the endsof the sections lcomprising the wall of the outer flue t in under the enlargement and abut against flange 7 as'clearly shown in said ligure.

In the form illustrated in Fig. 12 the inner flue is made in four sections which are assembled in a slightly different way, and the portion ofthe outer flue above the roof is made angular instead of round as will be again referred to.

The ends of the sections of both the inner and outer iiues are provided with off-sets 17 either outward or inward as may be required to engage the unions as clearly shown in Fig. 4. This is in order to leave the inner surface of the inner line smooth and unobstructed and the outer surface of the outer iiue likewise smooth and free from projections or enlargements. The unions consist of an IOO inner tube 13 and an outer tube 14 which are connected at approximately their mid-.length by cross pieces 15. The unions may or may not be provided with outer lianges 16 adapted to rest upon a ioor or roof. Where a union is intended to carry a damper the cross pieces are made as in Fig. 7 and the dampers 18 are made to correspond therewith sothat when the cross pieces of the damper and union register the damper will be open and when moved to the opposite positionthe damper will be closed. Where the union is only. intended to secure sect-ions of the inner and outer tlues together I preferably provide them- Withfour ,with hubs 19 which extend through the outer iue and are adapted to receive stove-pipes 20 iii-required from any of the rooms. When it is not desired to attach a stove pipe the hub is closed by a cap 2l, see Fig. 1.

22 denotes a damper near the top of the room and 23 a damper near the bottom of the room both leading into the outer flue. These dampers are provided with lugs 24 on opposite sides which are connected by means of cords 25, said dam pers being soy arranged that when one is open the other is closed. The dampers 18 are provided with hand pieces 26 which extend out into the room and permit the operator to open or close the damper as may be required for proper use in connection with dampers 22 and 23.

In addition to being durable, inexpensive and perfectly safe my novel chimney being built in sections and the sections being connected to the different parts of the house, will settle at alltimes to correspond with the house so that there will be no danger to the chimney fromsettling. The construction is such as to utilize all the heat radiated from the inner flue for the purpose of warming air in the outer flue which may be used for heating purposes or to assist in ventilation.

My invention lies in the construction of the chimney and not in any special use to which it may be placed.

The use in connection with the hot air chamber of a furnace will be apparent. Suppose for instance that outer iue B is connected with the hot air chamber of a furnace and that it is desired to heat a room as in Figs. 1

and 2. The hubs 19 would be closed by caps 21 and damper 18 in the unionwould be closed by means of hand piece 26. This would prevent the passage of the hot air in the outer flue out at the top thereof and would permit it to pass out into the room when required. Dampers 22 and 23 would then be moved to the position shown in Fig. 1 the upper damper being closed and the lower damper open.

This would prevent the passage of air out of the roomintoy the outerl flue. andwould permit the heated air in the outer iue to pass out into the room. Should it be desired to combine heating and ventilation dampers 22 and 23 would be turned to an intermediate position in which. each is partially-open.. This Would permitheated air from below damper 18 to pass out into the room and would per- Y the outer fiue which may be allowed to pass lout into the rooms as already described, and fthe air in the rooms may be allowed topass out into the iiues as has also been clearly described.

As shown in the drawings anges 7 are outer flue into two or more entirely separate compartments which is preferable in a double house and in houses constructed to rent in flats.

Where my novel chimney is used in a single house, openings, not shown in the drawings, may be cast in the flanges so that the youter iiue will comprise but asingle compartment. The inner and outer ues are both eX- tended upward as far above the roof as may be required and are `preferably covered by a cap 27.

It will be apparent that my novelchimney is admirably adapted for cooling and ventilating purposes in warm Weather without any changes Whatever.

In Figs. 10 to 13 inclusive Ihave illustrated a form in which the wall of the outer iiue is made angular above the roof. The number vof sections of which either the inner or the outer iiues are constructed is of course not of the essence of my invention.

In Fig. 12 I have shown the inner flue as made in four sections each sectionl having a liiange 7 with an enlargement 9 at its outer l end, said iianges lying at right angles to each` otherand supportingthe plates 28 which coml prise the angular portion of the chimney Sabove the roof and which are secured to said ienlargements. When the chimney is made in this form the portion above the roof may be supported in any preferred manner.

In Figs. 10, 11 and 13 I have illustrated' a simple` and practical mode of bracing and zholding the portion above the roof. 29denotes plates which I term roof plates and which are pivoted to each otheras at 30. The `upper ends of these platesy slide one under the other in depressions 31 in the ends ofthe i chimney, the upper ends of said depressions terminating in inwardly extending curved `flanges 32, see Fig. 12. The upper ends 0f fated therefrom necessarily war-ms -the air ink made solid. This is in order to divide the ICO these plates are rigidly secured to the end plates 2S of the chimney by means of bolts 33 which are xed in one of said plates and pass through slots in the other plate. It will be seen that this adjustment permits the lower inner edges of the roof plates indicated by 34, to conform to the pitch of the roof. 35 denotes cross plates between the roof plates which are vprovided with end flan ges 36 which are bolted to the roof plates as clearly shown, and with top fianges 37, see Fig. 13 upon which the angular portion of the chimney rests, the lower side plates of the chimney being preferably provided with flanges 38 see Fig. 12, which rest upon iianges 37 as will be apparent from Figs. 10 and 13 in connection with Fig. 12.

Having thus described my invention, I claiml. A chimney comprising an inner line whose wall consists of portions 5 each of which is adapted to abut against the edge of another portion and is provided with a ange 7 and with lugs 6 adapted to be bolted to said flanges, and an outertlue whose wall likewise consists of sections, and unions consisting of inner and outer tubes connected together by cross pieces by `which the sections of the inner and outer tlues are connected together.

2. The interchangeable sections b each consisting of a portion 5 adapted to abut against a corresponding section, a flange 7 and lugs 6 by which it is attached to the corresponding section.

3. A chimney consisting of inner sections a and outer sections b joined together by unions C said sections a comprising portions 5, grooves 8 to receive the edge lof the other portion, flanges l7 having cross flanges 9 and lugs 6 for attachment to flanges 7, and said sections b being provided with enlargements having recesses 12 to receive the cross flanges.

et. A chimney consisting of inner sections a and outer sections b, said inner sections being provided with danges 7 by which said sections are secured together and to the outer sections and said inner aud outer sections being provided with o-sets 17, and

unions comprising inner and onter tubes which receive the oit-sets on the inner and outer sections between them, and which are secured together by cross pieces 15.

5. The combination with inner iiue A and outer tlue B each made in independent sections, of unions consisting of inner and outer tubes connected by cross pieces which receive the ends of the sections between them, and dampers resting on said cross pieces by which the passage of air in the outer line may be cut oi at any time.

6. The combination with the inner flue and the outer Hue provided with dampers 18 said inner iiue having hubs 19 extending through the outer flue, of dampers 22 and 23 in said outer ilue surrounding the hubs, and caps for closing said hubs when required.

7. In combination plates 28, roof plates 29 pivoted to each other and having inner edges adapted to correspond with the angle of a roof, and suitable means for locking said plates together and to plates 28 and cross plates 35 having end flanges by which they are bolted to the roof plates.

8. The combination with plates 28 comprising the angular portion of the chimney, of the sectional inner flue having flanges 7 to which plates 28 are secured, root plates29 pivoted to each other and adjustably secured to plates 28, and cross plates lying between the roof plates.

9. The combination with plates 28 comprising the angular portion of the chimney two of said plates having depressions 31 and the other two having ianges 38, of the sectional inner fine having flanges 7 to which plates 28 are secured, the roof plates pivoted to each other and adjustably secured in depressions 31, and cross plates 35 having end danges which are bolted to the root plates and top flanges 37 upon which plates 28 rest.

In testimony whereof I affix my signature in presence of two witnesses.
